Abstract

:

The identification of most the effective individuals in a dynamic social network can be utilized to better understand and control the behavior of network nodes. Since most of real-world social networks have social characteristics and time-varying features, it is non-trivial to study the importance of social attributes of individuals on the key player identification problem. In this paper we investigate the inter-relationship between some important social features such as the flexibility and sociability of individuals with the importance of their roles in dynamic social networks. Particular applications are used for information diffusion through the network. To this end, a dynamic network model was designed to provide definitions for individuals’ social attributes, and describe opinion transfers between them. By means of simulations, the effectiveness level of various sets of individuals in information diffusion is investigated. By selecting sets of players from different regions, the relations between these social features and the importance of the individual’s roles are revealed.
